Abstract

This paper presents a fast and efficient way of simulating multistage power electronic circuits with stages operating at widely separated frequencies, using the Norton transmission line modelling (TLM) technique. A multistage circuit can be decoupled into several sub-circuits which can then be simulated individually with different time steps according to their circuit time constants. Energy exchange between linked sub-circuits are made possible via the use of a stub-link conversion technique. Simulation is carried out using a forward voltage converter circuit. Results are compared with those from PSpice. 1 Introduction Many power electronic circuits consist of several power stages which operate at wid
